Electrocardiographic Imaging as Preoperative Tool in Persistent and Long-Standing Persistent Atrial Fibrillation: A Prospective Observational Study.

ABSTRACT:

Objectives

Surgical ablation for treating atrial fibrillation (AF) is currently performed mostly without preoperative electrophysiological imaging. This study aimed to investigate the use of non-invasive surface mapping as a preoperative tool to explore potential mechanisms and patterns involved in the electrophysiology of persistent and long-standing persistent AF.

Methods

This prospective, observational study included cardiac surgery candidates without previous ablation. Bi-atrial epicardial activation sequences were obtained with electrocardiographic imaging and analysed in an independent core lab. Statistical analyses included hierarchical clustering, which quantified 3 clusters based on the number of drivers to identify specific characteristics.
